According to the American College of Obstetricians and Gynecologists (ACOG), swimming is one of the safest forms of exercise during pregnancy. Swimming does not place a high level of stress on the body and offers many health benefits. It relaxes muscles and joints, reduces swelling, and alleviates morning sickness.

What should be taken into consideration?

Swim only in areas that you know are safe and are certain of their cleanliness.

To prevent sunburns, use broad-spectrum sunscreens with a minimum SPF of 30 when swimming outdoors. Don’t forget to reapply sunscreen frequently and try to avoid swimming outdoors between 10 a.m. and 4 p.m.

Being in the water may suppress your sense of thirst. Make sure to drink plenty of water.

During pregnancy, you may tire more easily than when you are not pregnant. Before going swimming, don’t forget to check the tides and whether the water is rough.

What about chlorine?

To minimize the risk of infection, swim in clean and well-maintained pools. Chlorine levels within the acceptable range in pools are not associated with adverse pregnancy outcomes.

Beware of hot tubs!

Swimming in very hot water should be avoided during pregnancy. High body temperatures can cause birth abnormalities or miscarriages. Swimming in extremely cold weather and cold waters can also be dangerous.

Consult your doctor.

Although swimming is considered safe during pregnancy, it may be risky for pregnant women with certain medical conditions or activity restrictions due to pregnancy complications. Therefore, consult your doctor before starting to swim.
